move_uploaded_file

(PHP 4 >= 4.0.3, PHP 5)

move_uploaded_file -- Moves an uploaded file to a new location

Description

bool move_uploaded_file ( string filename, string destination )

This function checks to ensure that the file designated by
filename is a valid upload file (meaning
that it was uploaded via PHP's HTTP POST upload mechanism). If
the file is valid, it will be moved to the filename given by
destination.

If filename is not a valid upload file,
then no action will occur, and
move_uploaded_file() will return
FALSE.

If filename is a valid upload file, but
cannot be moved for some reason, no action will occur, and
move_uploaded_file() will return
FALSE. Additionally, a warning will be issued.

This sort of check is especially important if there is any chance
that anything done with uploaded files could reveal their
contents to the user, or even to other users on the same
system.

Note: move_uploaded_file() is both safe mode
and open_basedir
aware. However, restrictions are placed only on the
destination path as to allow the moving
of uploaded files in which filename may conflict
with such restrictions. move_uploaded_file() ensures
the safety of this operation by allowing only those files uploaded
through PHP to be moved.
